It's funny, as I watched the Bills lose again to KC, a trade for Hill went through my head. Not only is he a great WR and a huge threat, it's a shot at KC since he had so much success there.
Doubtful it happens, since Miami is involved, but his skill would transform our offense.
IMO, and this is more of a pipedream, you leave the offense and Brady to grow together this year. But McD gives up the defense, you bring in a real DCoordinator who has recent success, and rebuild the defense. They've given it 8 years and the D has been solid, but once the ceiling is reached in the playoffs, they fold.
